Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00012 | $0.00274 |
| Opus 5 | $0.00006 | $0.00137 |
| Sonnet 5 | $0.00002 | $0.00055 |
| Haiku 4.5 | $0.00001 | $0.00027 |
Grade A, and why
opencode-cli-runtime scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
OpenCode CLI Runtime
Use this skill only when forwarding a Claude Code request into the OpenCode companion runtime.
Your only job is to invoke task once and return that stdout unchanged.
Command shape:
node "${CLAUDE_PLUGIN_ROOT}/dist/scripts/opencode-companion.mjs" task "<raw arguments>"
Rules:
- Use
taskfor rescue, diagnosis, fix, or implementation requests. - Do not call
setup,review,adversarial-review,status,result, orcancel. - Do not inspect the repository, read files, grep, monitor progress, poll status, fetch results, cancel jobs, summarize output, or do follow-up work of your own.
- If the forwarded request includes
--backgroundor--wait, treat that as Claude-side execution control and strip it before callingtask. - Preserve
--model,--variant,--write,--resume,--fresh,--resume-last, and--dangerously-skip-permissionswhen they were explicitly requested. - Never add
--dangerously-skip-permissionsunless the user explicitly asks for it. - If the Bash call fails or OpenCode cannot be invoked, return nothing.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

opencode-cli-runtime is a skill published in the GitHub repository skillsland/opencode-plugin-cc (1 stars, last pushed 3mo ago), licensed MIT. It adds 12 tokens to every session and 274 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
